To all whom it may concern:

Be it known that we, FREDRIK LJUNG- I sT z'oM and Ismon BROBERG, subjects of the 4 King of Sweden, residing, respectively, at

.The present invention relates to arrangements in locomotive condensers and princlpally refers tothe location. of the cooler and that ofjthe receptacle for the water of condensation, condensers of an elongated shape provided with cooling elements extending transversely thereof being particularly considered.

Theinvention primarily consists therein that the steam supply pipe is disposed in the centre of the condenser, or approximately so, extending longitudinally thereof, the said pipe forming a supporting frame for the cooling elements, which latter incline downward-1y toward the sides of the condenser where they are connected with two collecting pipes for the water of condensation, one of such collecting pipes being disposed on either side of the condenser.

The invention also consists in the two collecting pipes for the water of condensation being connected with one another, or with the steam supply pipe, by means of two hollow stays of such material as to render the expansion of the stays and that of the elements coincident.

The invention further consists therein that the fans required for producing a circulation of the air are disposed on the steam supply pipe of the cooling elements so that they will force the air to flow in an upward direction.

The invention still further consists in the collecting pipes being connected with the steam receptacle by means ofbranch pipes which, together withthe supply pipe, carry the air cooler.

In the accompanying drawing wherein the preferred embodiment of the invention is illustrated,

cates the receptacle for steam and water of condensation, said receptacle being of elongated cylindrical form. The receptacle 1 is provided with an-inlet 16 for steamand an outlet 17 for the water. The cooling. elements 2 extend transversely of the condenser andare located between the steam supply pipe 3 and the conducting pipes 4 for the water of condensation. The pipe '3 forms a support for the upper ends of the elements 2 and the pipe 3 is supported upon the receptacle 1 by pipes 8 by which steam is conducted to the pipe 3. The collecting pipes 4 are connected with each other or with the supply pipe 3 by means of hollow stays 5 and with the steam space of the receptacle'l by means of branch pipes 6 which latter, together with the steam pipe 3, carry the air cooler. In order to render accessible the elements 2 which latter incline' from the center of the condenser down- 17 5- wardly toward the sides thereof, the condens er is provided with a platform or bridge 7 arranged above the steam supply pipe 3. As will appear from Fig. 1 the steam having entered the receptacle 1 through the inlet 16 O ascends in part through the pipes 8 to the pipe 3 and from the latter pipe the steaml i The stays 5 consists preferably of pipes one end of which is connected with one pipe 4. The other end of each. pipe 5 is, as shown in Fig. 1, connected with the pipe 3. Additional stays 5 extend between and By this arrangement the-stays 5 are heated and if they are made of a material the expansion of which coincides with that of the elements 2, objectionable stresses in the stays will be avoided. The fans 9 employed to produce .a circulation of the air, are disposed between the receptacle 1 and the elements 2 located thereabove, the said" fans being preferably pivoted to. the"- steam supply pipe 3m 2 horizontal position so as to force the air to flow in upwardly directed currents past the cooler.

The elements 2 may be arranged in one or more groups, consecutive groups decreasing'in size toward the air pump, if desired.

What we claim as new and desire to secure by Letters Patent of the United States is 1. In a locomotive condenser, the combination of a receptacle for, steam and water, cooling elements extending transversely thereof, a steam supply pipe connected with said cooling elements, and pipes connecting the receptacle with said steam pipe, said latter connecting pipes together with the steam pipe supporting one end of the cooling elements.

2. In a locomotive condenser," the combination of a receptacle for steam and water, cooling elements extending transversely thereof and inclining downwardly toward the sides of the condenser, a steam supply pipe' connected with said cooling elements, and pipes connecting the receptacle With said steam pipe, the last mentioned connecting pipes together with the steam pipe supporting one end of the cooling elements.

3. In a locomotive condenser, the combination of a receptacle for steam and water,

cooling elements extending transversely thereof, collecting pipes for the water of condensation, asteam supply pipe extending parallel to the condenser and connected with said cooling elements, and pipes connecting the receptacle with said steam pipe, said latter connecting pipes together with the steam pipe supporting one end of the cooling elements.

4. In a locomotive condenser, the combination of a receptacle for steam and water cooling elements extending transversely thereof and inclining downwardly toward the sides of the condenser collecting pipes for the water'of condensation, a steam supply pipe extending in the longitudinal direction of the condenser and connected with said cooling elements, and pipes connecting the receptacle with said steam pipe, the last mentioned connecting pipes together with the steam pipe supporting one end of the cooling elements.

5. In a locomotive condenser, the combination of a receptacle for steam and water, cooling elements extending transversely thereof, collecting pipes for the water of condensation extending along the sides of the receptacle, a steam supply pipe extending in the direction of the collecting pipes and connected-with said cooling elements, hollow stays connecting said collecting pipes with said steam pipe, and pipes connecting the steam pipe with the receptacle, the connectingpipes together with the steam pipe supporting one end of the cooling elements.

6. In a locomotive condenser, the combination of a receptacle for steam and Water,

cooling elements extending transversely thereof, collecting pipes for the water of condensation extending along the sides of the condenser, a steam supply pipe connected with said cooling elements, hollow tubular stays connecting said collecting pipes with said steam pipe, and pipes connecting 'the steam pipe with the receptacle, the consteam pipe forming a supporting structure for the cooling elements.

8. In a locomotive condenser, the combination of a receptacle for steam and water, cooling elements extending transversely thereof, collecting pipes for the water of condensation extending along the sides of the condenser, a steam supply pipe connected with said cooling elements, branch pipes connecting the collecting pipes with the receptacle, and pipes connecting the steam supply pipe with the receptacle. said latter connecting pipes together'with the. branch pipes and the steam supply pipe forming a support for the cooling elements. j

9. In a locomotive condenser, the combi nation of a receptacle for steam and water, cooling elements extending transversely thereof, a steam supply pipe extending in the longitudinal direction of the condenser and connected with said cooling elements, fans pivoted to said steam supply pipe, and piples connecting the latter with. the receptac e.
